Abstract: 1,209,289. 209, 289. Automatic current and voltage control. MITSUBISHI DENKI K. K. Sept. 15, 1969 [Feb.7, 1969], No.45305/69. Heading G3R. [Also in Division H2] Traction motors 50 are supplied from a D.C. source through choppers 21, 22, -2n, in series with, flywheel diodes 31, 32, -3n, associated with reactors 41, 42, -4n. The choppers have gate electrodes G1, G2, -Gn, connected to the controller 60 whereby the choppers are opened and closed in succession at predetermined intervals. If there are n choppers, the ratio of conduction time to chopping period of each chopper is equal to an integral multiple of the reciprocal of n whereby the ripple content of the motor current is reduced, so preventing external interference. A main controller MC for the motors has several notches for series-parallel and fieldweakening control, the motors being adapted for continuous operation on one or more of these notches. A unit CA compares actual and desired values of the motor current. Phase-shifters PS1, PS2, - PSn are operated successively at intervals by pulses from distributer DB associated with oscillator DSC, and respond to the error voltage from comparator CA to determine the on-time of the choppers. A voltage-limiter VL is connected to transformers DCPT1, DCPT2, detecting the input and motor voltages respectively. If the voltage across the motor set exceeds the limit established by the unit VL, a control signal is applied to the unit CA for opposing the reference voltage. The voltage limit is selected to render the ratio between the conduction time and chopping period equal to an integral multiple of the reciprocal of n. Dynamic braking can be introduced at a higher speed than normal.

To prevent the cutter assembly and pinch roller assembly from slipping off their supporting pins 240 and 242, Fig. 5, the support member 220 has mounted thereon a bridge 280 having downwardly extending walls 281 and 282, which, when either the cutter assembly or pinch roller assembly is operative, abut the arm 250. To remove either of the assemblies, they are pivoted about the pins 240, 242 until they are free of the walls 281 and 282. The frame 160, Fig. 3, has end plates 161, 162 connected by a pair of parallel tie-rods 170, 172 between which the support member 220 extends. The member 220 has a recess 231, Fig. 6, for engaging the tie-rod 172 and a bushing 233 for receiving the tie-rod 170. A thumb screw 235 threadedly received in the bushing 233 engages a flattened surface 237 on the tie-rod 170 whereby the, or each, cutter unit 175 may be slidably adjusted. The roller 180 is driven from a motor 190, Fig. 3, by means of a chain 197 and sprocket wheels 195 and 198. A set screw 301, Fig. 6, carried by the support member 220 serves as a stop for the arm 250.

In an associative memory, each word store has a plurality of bi-stable devices associated with it, setting of ;any one of which enables a read or write signal subsequently to be applied to the word store, selection means being provided to set a selectable one of the bi-stable devices in response to the generation of a match signal. The associative store of Fig. 1 comprises: an input register 2; a mask register (with gates) 4; logic circuits 6; word stores 7 each bit position being capable of three states viz. 0, 1, nothing; a primary and a secondary trigger 16, 17 respectively (with logic) associated with each word store; an output register 9; and a decoder 19 which can produce any of the following operations: SELECT: those orders of the input register 2 which correspond to orders of the mask register 4 set at 1 are compared with corresponding orders of the word stores 7 (decoder output S energized), match setting either the primary or the secondary trigger (according as decoder output P or SY is energized). SELECT NEXT: like " select " only the primary or secondary trigger of the next word store is set on match, not that of the word store giving the match (decoder output N also energized). TRANSFER TO NEXT: the set state of each set primary or secondary trigger (depending on whether P or SY is energized) is transferred to the next such trigger (N energized). READ: those word stores whose primary or secondary triggers (depending on P or SY) are set are read out to the output register 9 simultaneously (so that if there are a plurality of such word stores corresponding bits are ORed on the column lines 11, 12) and in any event only those positions at which the mask register 4 holds 0 are gated at 71 to the output register 9 (decoder output R energized). WRITE: contents of input register 2 at those orders corresponding to orders of the mask register 4 set at 0 are written into those word stores having the primary or secondary trigger set (depending on P or SY; W also energized). SET MASK: input register 2 loads the mask register 4 (SM energized). SWITCH: output SW of decoder 19 is energized to overrule the selective effects of the mask register 4. Combinations of the above operations are possible. In a computer, accessing of instruction words belonging to the main programme and to subroutines may be controlled by the primary and secondary triggers respectively TRANSFER TO NEXT followed by READ can be used for stepping through a set of consecutive instructions, a branch being initiated by using SWITCH as well.
